2 Introduction to the Project Existing MVC Plans / Studies (AFW Prepared) Rural Road Study (2001) County Collector Network and Road Standards (2006) County Collector Network Construction Study (2007) Grid Road Study (2008) - Incomplete Need for a Local Road Management Plan Understand impacts of short-term, highintensity development traffic including: Construction / Commercial Development Activities; Oil & Gas Exploration Activities; Movement of Goods and Materials; Determine current condition of local roads to facilitate prioritizing of future maintenance and capital improvement efforts 1

3 Project Objectives & Deliverables Objective: Establish and quantify the cumulative financial implications (maintenance funds) of increased use of MVC s road network resulting from short-term, high-intensity development related traffic Deliverables: Road Use Study Method for use by MVC staff to assess a fee to Road Use Permit Applicants for the cumulative impact their proposed work (increased traffic) has on MVC s local road network Grid Road Study Database of existing local road condition ratings and criteria for rehabilitation / reconstruction, which can be used to generate road improvement and maintenance schedules for MVC s planning, programming, and expenditure forecasting purposes 2

4 Fee for Industry Road Impact Anticipated End Result Form to be used in conjunction with MVC s GIS system at the time a Road Use Permit Application is received for a given development or activity that will add additional truck traffic to MVC s road network over a short-term duration. 3

5 Fee for Industry Road Impact Anticipated End Result The User inputs the following data from the Road Use Permit Application: Route to be taken (made up of Road Segment ID s selected from a GIS map); Number of loads (i.e. trucks) per day to be introduced to the network; and, Number of days those loads will be present; The User will query the GIS database to determine the lengths and $ / Load kms factors for each Road Segment ID; The Form will calculate Load kms, Cost, and the ultimate Fee for Industry Road Impact to be recovered from the Applicant. 4

6 Fee for Industry Road Impact Data / Input Required MVC Truck Route Map Network and Non-network roads No bridges with weight bans No dead ends Input from MVC s Foremen and Grader Operators Existing volumes of truck traffic (background truck traffic) 2010, 2011, and 2013 traffic counts; All counts factored to 2013 Truck Average Annual Daily Traffic (TAADT) volume assigned to every Road Segment ID Where TAADT was zero, the 2013 calculated average TAADT was applied: Network Roads: 18 Non-network Roads: 4 Quantification of current maintenance efforts for all roads 2014 budgeted road maintenance costs 5

7 Fee for Industry Road Impact Data / Input Required Activity Cost / Kilometre Gravel Road Maintenance $ 6, / km Chip Seal Road Maintenance Asphalt Concrete Pavement (ACP) Road Maintenance $ 18, / km $ / km Gravel Road Maintenance includes costs for surface grading, re-shaping, re-gravelling, and base repairs Roads identified as typically requiring more maintenance were assigned an increased (pro-rated) maintenance cost / km Chip Seal Road Maintenance includes costs for re-chipping on a sevenyear cycle and patching / pothole repairs ACP Road Maintenance includes costs for patching / pothole repairs and crack sealing 6

8 Fee for Industry Road Impact Methodology Maintenance efforts for any road surface type are primarily attributed to the truck traffic (loads) experienced on that roadway Calculation of Load kms and Cost used by the Form: where: Loads / Day is determined from the Road Use Permit Application; Days is determined from the Road Use Permit Application; Length is determined from the GIS database for each Road Segment ID; Calculation is multiplied by two (2) to account for bi-directional traffic. 7

9 Fee for Industry Road Impact Methodology Calculation of $ / Load kms factor: where: $ / km MAIN is based on budgeted maintenance activity costs / km; Length is determined from the GIS database for each Road Segment ID; Load kms EXG is derived from the existing (2013) TAADT. 8

10 Fee for Industry Road Impact Example MVC receives a Road Use Permit Application from an Applicant that will introduce heavy truck traffic onto the network over a short-term period MVC staff enter the following information into the Form from the received application: Information Required Information From Permit Route From Highway 27, South on Range Road 3.5, No. of Loads / Day 35 No. of Days 2 East on Township Road 32.0, South on Range Road 3.4, East into property The User then selects the Road Segment ID s for the route from the GIS Truck Route Map 9

11 Fee for Industry Road Impact Example 10

12 Fee for Industry Road Impact Example The following information will be returned from the GIS database: Road Segment ID Network or Non-network Surface Type Length (km) Existing TAADT Load kms EXG $/km MAIN $/Load kms R35T325 Network Gravel ,018 $ 6, $ 0.53 R35T324 Network Gravel ,105 $ 6, $ 0.53 R35T323 Network Gravel ,363 $ 6, $ 4.50 R35T322 Network Gravel ,580 $ 6, $ 4.50 R35T321 Network Gravel ,722 $ 6, $ 2.25 R35T320 Network Gravel ,719 $ 6, $ 2.25 T320R34 Network Chip Seal ,567 $ 18, $ 0.63 R34T315 Non-network Gravel ,687 $ 7, $

13 Fee for Industry Road Impact Example The Form will calculate the Load kms, Cost, and indicate the Total Fee for Industry Road Impact: Road Segment ID Length (km) $/Load kms Load kms Cost R35T $ $ R35T $ $ R35T $ $ 1, R35T $ $ R35T $ $ R35T $ $ T320R $ $ R34T $ $ Total Fee for Industry Road Impact: $ 3,

14 Grid Road Study Methodology Included a mile-by-mile assessment of the entire local road network (approximately 2,800 km of roads) Data collection: Previously completed assessments (from 2008) were reviewed and updated Remaining assessments undertaken by MVC staff (July September 2013) Training session with MVC staff held prior to inspections AFW input completed inspection forms into a digital database Information used to identify roads that require significant maintenance and / or capital expenditures to either restore or improve their condition, level of service, and / or geometrics Provided all assessment data to MVC for their use in sorting, ranking, prioritizing, and tracking road improvements throughout the County 13

15 Grid Road Study Condition Assessment Ratings Road segments were assessed based on four criteria: Horizontal Alignment (i.e. curves); Vertical Alignment (i.e. hills, valleys); Surface Width; and, Surface Condition. Each component was visually rated on a scale from 1 to 5: 1 Unsafe; Possible Closure 2 Poor; Requires Improvements 3 Satisfactory 4 Good 5 Excellent 14

16 Grid Road Study Condition Assessment Ratings Overall Condition Scores were calculated for each road segment based on the following weightings: Condition Assessed Percentage of Overall Rating Horizontal Alignment 40 % Vertical Alignment 30 % Surface Width 20 % Surface Condition 10 % Total: 100 % 15

17 Grid Road Study Construction Plans Road segments were ranked and prioritized based on the Overall Condition Scores Roads with a rating of one (1) or two (2) for any condition were moved to the top of the ranked list Ranking priority was given to horizontal and vertical deficiencies over existing surface width and condition 5- and 10-Year Construction Plans were developed and consider: MVC s Area Structure Plans Growth regions and natural resource development areas AFW s local knowledge Consultation with MVC staff Construction Plans consider the annual completion of upgrades / improvements to ten (10) road segments (average 16 km / 10 miles) 16

18 Grid Road Study Enhanced Maintenance Roadways Developed separate priorities list for potential improvements / upgrades to roads that receive increased maintenance attention 45 road segments received a 2 rating for one of the condition assessment criteria: Horizontal Alignment 6 road segments; Vertical Alignment 6 road segments; Surface Width 1 road segment; and, Surface Condition 32 road segments. 17

19 Local Road Management Plan Summary and Recommendations The following information was provided to MVC in electronic format: Digital copy of all traffic count data and calculated maintenance costs; Form to be used at the Road Use Permit Application stage to calculate the Fee for Industry Road Impact; Database containing all information fields to support the Fee for Industry Road Impact calculations and Form inputs (MVC to develop Truck Route Map within their GIS database); Digital copies of all field collection data sheets from the Grid Road Study; and, Database of Grid Road Study data, ratings, and scores (MVC to develop GIS database layer). 18

20 Local Road Management Plan Summary and Recommendations The following recommendations were made: Collect new traffic data (AADT and TAADT) every three (3) to five (5) years, including a review of all count locations; Update typical maintenance costs annually in coordination with budgets; Update condition assessment visual inspections / ratings of all local roads on a five-year cycle; Completion of visual inspections by one (1) to three (3) Inspectors to help: Eliminate differences in opinions and subjectivity across multiple Inspectors; Minimize the occurrence of missed road segment assessments; Provide a more homogeneous approach to the evaluation of each road; Consider focusing funds on improving the road segments identified by MVC s Foremen / Grader Operators 19
